TROLLEY.

SPECIFICATION forming part of Letters Patent No. 707,338, dated August19, 1902. I

Application filed March 31, 1902.

To all whom it may concern:

Be it known that I, PERRY E. LOREE, a oitizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain newand useful Improvementsin Trolleys,of which thefollowing is a specification, reference being had therein to theaccompanyingdrawings.

This invention relates to trolleys, and more particularly to theconstruction and arrangement of the mounting of the trolley-wheel uponthe head provided therefor at the end of the trolley-pole; and it hasfor its object to provide animproved construction whereby the Wear uponthe wire and wheel arising from friction of lateral contact on curvesand from other causes may bediminished. v

To these ends my invention consists incortain novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of astructure embodying my invention. Fig. 2 is a rear elevation of thesame. Fig. 3 is r a vertical sectional view taken on the line a", wofFig. 2 and looking in the direction of the arrows. Fig. 4 is a verticalsectional view taken on the line 3 y of Fig. 3 and looking in thedirection of the arrows, and Fig. 5 is a plan view.

In the said drawings, 1 indicates the trolley-pole or a projection orarm of the device adapted to be secured thereto, and 2 indicates asawhole the head. This latter is provided with two rearwardly-extendinglugs 3 and 4 and also with two flanges 5, extending rear- Wardly fromthe sides of the lower lug 4 and connected near their rear ends by atransverse piece 6, which forms a track or way to be hereinafterreferred to.

7 indicates as a whole a carriage pivotally mounted on the head betweenthe lugs 3 and 1 by means of a pivot-pin 8, adapted to be secured by akey or cotter 9 or by any other suitable pivotal connection. The pivotalconnection between the carriage and head is at the front end of thecarriage and in ad- Vance of the trolley-Wheel spindle or axle, so thatthe trolley-wheel has a trailing swinging motion relatively to the head.Near the rear end of the base of the carriage 7 there is mounted thereinan antifriction wheel or Serial No. 100,745. (No model.)

roller 10, which rests upon the tracks 6, and thus relieves thefrictional strain between the carriage and head due to the pressurebetween the trolley wheel and wire. The carriage is also provided with adownward and forward extending lug 11, which engages under the track 6,so as to prevent upward motion of the rear end of the carriage. Therearends of the flanges 5 lie in the path of the body of this lug 11,and thereby form stops to limit the lateral movement of the carriage onthe pivot 8. The carriage 7 is provided with upwardly-extendingcheek-pieces 12, provided near their rear edges with outwardly anddownwardly inclined projections 13 for preventing the trolley-wire fromcoming into contact with and engaging the rear ends of the flanges 5 incase the wheel slips from the wire and is thrown to one side or theother. In these cheek-pieces-are formed apertures 14 to receive thespindle or axle 15, which may be secured in position by a key 16 or inany other suitable manner. This spindle is hollow, as indicated at 17,to form a reservoir for the lubricant, which is preferably in the formof a grease, the same beingintrodnced through one end of the spindle,which is openfor that purpose and which is adapted to be closed by ascrew-plug or other suitable closure 18. An aperture 19 is formed in thebottom of the spindle for the escape of the lubricant, and thetrolley-wheel, which is indicated at 20, is provided internally with acircumferential groove 21, filledwith a packing 22, of asbestos or othersuitable absorbent material not liable to'be injured by heat. permit theintroduction of oil orany other suitable lubricant in case that alreadyin the spindle becomes exhausted under circumstances which renders itsrenewal difficult or inadvisable, I provide in the closure 18 a fillingaperture or passage 23, and the cheekpiece 12 is provided with aprojection 24, extending out over the mouth of said aperture in such away as to protect the same without closing it.

25 indicates a spring-arm secured at one end to the top of the carriage,its other end bearing against the under side of the lug 3 and serving asa brush to insure a proper electrical contact at all times between thecarriage and trolley-head.

In order to 26 is a loop or eye for the attachment of thecontrolling-cord.

It will be observed that the trailing carriage in which thetrolley-Wheel is mounted is capable of swinging laterally to a limitedextent sufficient to enable the wheel to accommodate itself to curvesand to the changing positions of the car and wire, and thereby diminishthe lateral friction between the wire and trolley-wheel, thus increasingthe durability of both wire and wheel. It will also be seen thatsuitable provision is made for retaining the carriage in place bothlaterally and vertically without excessive friction. Provision is alsomade to prevent engagement of the wire with the head or carriage in caseof accidental displacement.

The heat developed by friction between the wheel and its spindle willmelt the lubricant, which latter will pass through the aperture 19 andbe absorbed by the asbestos filling in the groove of the wheel anddistributed therefrom to the bearing-surfaces of the wheel and spindle.The asbestos, while absorbent, is of such a character as not to beinjured by the heat developed.

I do not Wish to be understood as limiting myself to the precise detailshereinbefore described, and shown in the accompanying drawings, as thesame may obviously be modified without departing from the principle ofmy invention.

I make no claim herein to those features shown and described whichrelate to the lubrication of the device, as such features form thesubject-matter of a separate application filed by me May 31, 1902, andbearing the Serial No. 109,705.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a trolley, the combination, with a pole provided with a headhaving rearwardly-extending lugs and rearwardly extending flangesconnected near their rear ends by a transverse piece or Way, of acarriage pivotally mounted at its forward end between said lugs andprovided at its rear end with an antifriction-wheel to bear upon the wayand with a lug located between the flanges and extending under the way,said carriage having mounted thereon rearward of its pivot atrolley-wheel, substantially as described.

2. In a trolley, the combinati0n,with a head having rearwardly-extendinglugs and rearwardly-extending flanges, of a carriage provided with atrolley-wheel pivotally mounted at its forward end between the lugs andprovided near its rear end on opposite sides with downwardly-divergingprojections forming guards to prevent the engagement of the trolley-Wirewith the flanges, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
